Tax Tips & Traps for Software Engineers

- →RSU income is taxed where you worked during the grant-to-vest period, not just where you vest.
- →Romania's IT workers exemption applies only to employers certified under Romanian law — contractor structures differ.
- →Portugal IFICI requires application within 60 days of registering as a tax resident — missing this window loses the benefit.
Software Engineers Tax FAQ
Do US citizen software engineers owe US tax when working abroad?
Yes. US citizens owe federal tax on worldwide income regardless of where they live. The Foreign Earned Income Exclusion (FEIE) shelters up to $132,900 of earned income in 2026, and the Foreign Tax Credit (FTC) credits foreign tax paid. You still must file every year.
How are RSUs taxed when an engineer works across multiple countries?
RSU income is generally apportioned by the workdays you spent in each country during the grant-to-vest period, not just where you live at vesting. Both countries may claim a slice; double-tax treaties usually resolve overlap, but the calculation requires careful tracking.
Who qualifies for Romania's IT workers income tax exemption?
Only employees of a Romanian-certified employer working on software development tasks qualify, on monthly gross salary up to RON 10,000. Independent contractors, consultants invoicing through a PFA or SRL, and employees of non-certified companies do not.
When must I apply for Portugal's IFICI regime to qualify?
You must register as a Portuguese tax resident first, then apply for IFICI within 60 days of that registration (or by 31 March of the following year — whichever is later under current rules). Missing the window typically forfeits the benefit and leaves you on standard progressive rates.
